"[You have to] realise when you are 'middle-aged' you have a chance for a whole second career, another love, another life," Stone said.

"You may be sick of what you did the first half of your life, but you don't have to just walk around and play golf or doing nothing. It's not like 50 is the new 30. It's like 50 is the new chapter."

Stone added that she has "come close" to having cosmetic surgery in the past, but has always ultimately resisted.

"Frankly, I think that in the art of ageing well there's this sexuality to having those imperfections. It's sensual," she added.

The actress continued: "If you have things that you want to fix, you should go right ahead and fix them. I don't think there is anything wrong with cosmetic surgery at all. I think it's great. But I don't think it's alright to distort yourself."
